Connect to HPCC Systems from a Connection Pool in WebLogic

Use the CData JDBC Driver for HPCC Systems to connect to HPCC Systems data from Web applications running on WebLogic.

The CData JDBC Driver for HPCC Systems enables you to follow standard procedures to integrate HPCC Systems data into Java Web applications. This article shows how to deploy the CData JDBC Driver for HPCC Systems in WebLogic server.

Install the JDBC Driver in WebLogic Server

Add the driver JAR and license file to the classpath your application will be using. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, add the JAR to the WEBLOGIC_CLASSPATH environment variable. add the following line to the commEnv.cmd/sh script in WL_HOME\common\bin\.

set WEBLOGIC_CLASSPATH=your-installation-directory\lib\cdata.jdbc.hpcc.jar;%WEBLOGIC_CLASSPATH%

If you want to add the driver to a specific domain, you will need to add the JAR to the PRE_CLASSPATH environment variable. Add the following line to the setDomainEnv.cmd/sh script in the bin subfolder of the folder for that domain:

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.hpcc.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for HPCC Systems

After installing the driver, create the connection.

  1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
  2. On the JDBC Data Source Properties page, enter the following information:
    • Name: Enter a user-friendly name; for example, hpccjdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/HPCC.
    • Database Type: Select Other.

  3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

    • Driver Class Name: Enter the driver class, cdata.jdbc.hpcc.HPCCDriver, in this property.
    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:hpcc:URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;

      接続するには、次の接続プロパティを設定します。Url をサーバーのマシン名もしくはIP アドレス、およびサーバーが起動しているポートに設定します。例えば、https://server:port。Url で指定されたHPCC システムへの認証には、User およびPassword が必要です。LDAP 認証は、現在サポートされていません。

      Version をWsSQL Web サーバーのバージョンに設定します。HPCC サーバーにWsSQL サービスをインストールしておく必要があることに注意してください。本製品は、HPCC システムへの連携にWsSQL Web サービスを使います。

      Cluster をターゲットクラスタに設定します。

    • Database User Name: Enter the username, if not specified in the JDBC URL.
    • Password: Enter the password, if not specified in the JDBC URL.

After selecting the server where you want to deploy the JDBC data source, you can now connect to HPCC Systems data.

More WebLogic Integration

The steps above show how configure the driver in a simple connection pooling scenario. For more use cases and information, see the JDBC sections in the WebLogic Data Sources chapter of the Oracle Fusion Middleware documentation.
